Stuxnet virus could target many industries

Stuxnet virus can be modified to wreak havoc on industrial control systems around the world.

Washington: A malicious computer attack that appears to target Iran`s nuclear plants can be modified to wreak havoc on industrial control systems around the world, affecting the production of everything from chemicals to baby formula, government officials and cyber experts warned on Thursday.

Experts told senators that attackers can use information made public about the so-called Stuxnet virus to develop variations targeting other industries, and that the worm`s consequences go "beyond any threat we have seen."

The code has attacked industrial sites in Iran and several other countries, and infected several employees` laptops at the Bushehr nuclear plans.

Iran has said it believes Stuxnet is part of a Western plot to sabotage its nuclear programme, but experts see few signs of major damage at Iranian facilities.

Specific industrial control systems using Windows software are vulnerable to the code. These are used in many critical sectors, from automobile assembly to mixing products such as chemicals and baby formula, Sean McGurk, acting director of Homeland Security`s national cyber security operations centre, told the Senate Homeland Security and Governmental Affairs Committee.

"This code can automatically enter a system, steal the formula for the product you are manufacturing, alter the ingredients being mixed in your product and indicate to the operator and your antivirus software that everything is functioning as expected," McGurk testified at a cyber security hearing.

Dean Turner, director of the Global Intelligence Network at Symantec Corp, told the panel that the worm showed that such attacks were possible. The "real-world implications of Stuxnet are beyond any threat we have seen in the past," he said.

But Turner added that the code`s highly sophisticated structure and techniques also could mean that it is a one-in-a-decade occurrence.

The virus is so complex and costly to develop "that a select few attackers would be capable of producing a similar threat," he said. "We would not expect masses of threats of similar sophistication to suddenly appear."
